新的Youtube api for android：获得视频标题

Question

我正在使用新的Youtube API for android。我已设法使用API​​显示特定的播放列表（使用ListView），点击列表中的视频后，我就可以播放该特定视频。

我的问题是这个。如何获取特定视频的详细信息？视频标题和视图数量等详细信息。我试过看YoutubeThumbnailView / loader，YoutubePlayerView，YoutubePlayer但没有运气。

这里是主要活动的代码，如果您需要更多信息，请告诉我。

非常感谢任何帮助。

public class MainActivity extends YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener, YouTubeThumbnailView.OnInitializedListener{


private final static String PLAY_LIST_ID = "XXX";
private final static String DEV_KEY = "XXX";

private YouTubeThumbnailView thumbnailView;
private YouTubeThumbnailLoader loader;
private ArrayList<HashMap<String, YouTubeVideo>> arrayList;
private ListView listView;
private SpecialAdapter adapter;
private int counter;
private YouTubePlayerView playerView;
private YouTubePlayer player;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    String[] keys = new String[]{"key"};
    int[] values = new int[]{R.id.imageView1};  
    arrayList = new ArrayList<HashMap<String, YouTubeVideo>>();
    setContentView(R.layout.activity_main);
    listView = (ListView)findViewById(R.id.listView1);
    listView.setOnItemClickListener(new onListClickListener());
    playerView = (YouTubePlayerView)findViewById(R.id.player);
    thumbnailView = new YouTubeThumbnailView(this);
    thumbnailView.initialize(DEV_KEY, this);
    playerView.initialize(DEV_KEY, this);
    adapter = new SpecialAdapter(this, arrayList, R.layout.row_layout, keys, values);
}


class onListClickListener implements OnItemClickListener{
    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
            long arg3) {
        playerView.setVisibility(View.VISIBLE);
        player.cueVideo(arrayList.get(arg2).get("key").videoID);
    }
}

@Override
public void onInitializationSuccess(YouTubeThumbnailView arg0,
        YouTubeThumbnailLoader arg1) {
    loader = arg1;
    loader.setPlaylist(PLAY_LIST_ID);
    loader.setOnThumbnailLoadedListener(new OnThumbnailLoadedListener() {
        @Override
        public void onThumbnailLoaded(YouTubeThumbnailView arg0, String videoId) {
            HashMap<String, YouTubeVideo> map;
            ImageView imageView;

            if(loader.hasNext()){
                map = new HashMap<String, YouTubeVideo>();
                imageView = new ImageView(MainActivity.this);
                imageView.setImageDrawable(arg0.getDrawable());
                map.put("key", new YouTubeVideo(imageView, videoId));
                arrayList.add(map);
                loader.next();
            }else {
                map = new HashMap<String, YouTubeVideo>();
                imageView = new ImageView(MainActivity.this);
                imageView.setImageDrawable(arg0.getDrawable());
                map.put("key", new YouTubeVideo(imageView, videoId));
                arrayList.add(map);
                listView.setAdapter(adapter);
            }
        }

        @Override
        public void onThumbnailError(YouTubeThumbnailView arg0, ErrorReason arg1) {
        }
    });
}

@Override
public void onInitializationFailure(YouTubeThumbnailView arg0,
        YouTubeInitializationResult arg1) {
}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}

@Override
public void onInitializationFailure(Provider arg0,
        YouTubeInitializationResult arg1) {

}

@Override
public void onInitializationSuccess(Provider provider, YouTubePlayer player,
          boolean wasRestored) {
    this.player = player;
}

@Override
  protected void onDestroy() {
    if(loader != null) {
        loader.release();
    }
    super.onDestroy();
  }

}
